Operation safety instructions  
WARNING: Stop the engine and unplug the spark plug  
before any repairs or maintenance operations.  
Check that all nuts, bolts and screws are well tightened  
before every use.  
Maintenance and storage  
Keep all nuts, bolts and screws tight to be sure the  
equipment is in safe working condition. Regular  
maintenance is essential for safety and performance.  
Before mowing ensure that the blade and the blade fixing  
screw are securely fastened. When the blade edges  
require re-sharpening, this must be done evenly on both  
sides to prevent any imbalance. If the blade is damaged,  
it must be replaced.  
Never store the equipment with fuel in the tank inside a  
building where vapour may reach a flame or a spark or a  
source of extreme heat.  
When mowing always wear long trousers and strong,  
covered footwear.  
Allow the engine to cool before storing in an  
enclosed space.  
Do not run the engine in an enclosed and/or poorly  
ventilated area. The gas of the engine contains carbon  
monoxide, which is dangerous to your health.  
To reduce the fire hazard, keep the engine, exhaust  
silencer, battery compartment and fuel storage area  
free of grass, leaves, or excessive grease. Do not leave  
containers with grass cuttings in rooms.  
Work only when there is sufficient light.  
Do not use the lawn mower when it is raining or when  
the grass is wet.  
Check the stone-guard and grass-catcher frequently for  
wear and deterioration.  
Caution must be taken while mowing on slopes. Mow  
across the face of slopes, never down or up.  
If the fuel tank has to be drained, this should be done  
outdoors and when the engine is cool.  
Turn off the engine if you must leave the lawn  
mower unattended.  
Wear strong work gloves when removing and  
reassembling the blade.  
Never lift the rear of the mower while starting the  
engine and never place your hands and feet underneath  
the deck while the engine is running.  
Check the blade’s balance after sharpening.  
For reasons of safety, do not use the equipment with  
worn or damaged parts. Parts are to be replaced and  
not repaired. Parts that are not of the same quality can  
damage the equipment and be dangerous for your safety.  
If working on high grass, adjust the mowing height to  
reduce the friction and prevent over loading. The optimal  
mowing height should be 1/3 the height of the grass.  
It would affect the work efficiency of lawn mower if too  
higher or lower.

release it until fully rewound.  
Mowing advice  
1. It is recommended to use the fast throttle setting and keep  
the engine running at maximum speed. This will deliver  
the best cut. If the speed of the engine slows this could  
indicate the mower is being overloaded, by trying to cut  
to much grass or the catcher may be full. Try mowing a  
narrower strip, mowing slower or raise the cutting height.  
4. Once the lawn mower has  
started and warmed up move  
the throttle lever to the either  
COLD START POSITION  
(recommended) or RUN while  
continuing to hold the brake  
lever.  
2. Sharp blades cut cleanly and efficiently, if the blade is dull  
it will tear the grass. This will result in the ends turning  
brown. When the blades no longer cut cleanly either  
sharpen them or replace them.  
3. To safely operate the mower ensure all four wheels are  
on the ground and be careful not to loose your footing  
or control of the mower. Be very careful when mowing  
uneven or rough ground. Keep a firm grip on the handle  
bar at all times, always walk, never run with the mower.  
11

4. For healthy growth, grass should not be cut too short.  
This can cause damage to the grass and allow weeds  
to develop.  
Maintenance  
Emptying the grass catcher  
Note. Before making any adjustment or maintenance  
procedures to the mower ensure it is turned off and the  
spark plug lead is removed.  
5. Vary your cutting pattern from week to week, this will  
help to prevent matting and graining of the grass.  
6. Before checking a clogged mower deck stop the engine  
completely and disconnect the spark plug lead and then  
tilt the mower so the air filter side is facing upwards.  
Use a stick the clear any clogged material, never use  
your hands.  
To remove the catcher, raise the guard while lifting the  
catcher to dislodge it from the hooks.  
WARNING. Check the catcher frequently for cracks and  
wear and replace it if damaged.  
Do not leave clippings in the catcher for extended periods.  
7. Mowing wet grass should be avoided. Wet grass will  
clog the mower deck and if it is slippery you may loose  
your footing.  
Replacing the blades  
WARNING. Stop the engine and unplug the spark plug  
before any repairs or maintenance operations.  
8. Always mow across slopes not up and down them.  
Be extra careful if the grass is wet as this could cause  
you to slip and loose control of the mower.  
WARNING. Never carry out any assembly operations or  
adjustments with the engine running.  
9. If the ground is to dry, mowing will stir up a lot of dust  
which may clog the air filter. In these conditions it is  
recommended to water your lawn the day before mowing.  
Note. Wear heavy gloves to protect your hands.  
Notes  
- Periodically check the blades (14) for nicks and dull  
cutting edges and have it sharpened if needed.  
10. Use the side of the mower as a guide to cut close to  
large objects such as a fence or a wall. Be careful when  
mowing over obstacles embedded in the lawn such as  
sprinkler systems and paving, avoid anything that sticks  
up above the surface of the lawn.  
- The blades should be sharpened and balanced by an  
authorised repair centre.  
- If there are rounded or broken  
ends, thinned metal or other  
damage, replace the blade.  
11. Avoid mowing over loose stones, gravel and other  
landscaping material as this can be picked up by the  
mower and flung out causing serious personal injury.  
1. With the engine switched  
off, remove the catcher and  
lift the front of the mower  
upwards so the handle bar  
sits on the ground and the  
spark plug faces upwards.  
12. If the blades do come into contact with something or the  
mower starts to vibrate stop the engine immediately,  
remove the spark plug lead and inspect to see if there  
is any damage.  
Note. Improper tipping may  
affect engine performance.  
2. Remove the blade disc with a  
spanner (not supplied).  
The central blade bolt must  
be removed first.  
12  
Download from Www.Somanuals.com. All Manuals Search And Download.  
3. Remove all 4 single blades  
including the washer and nuts.  
4. Clean the dirt and grass  
from around the blade  
mounting area.  
5. Replace all 4 blades to  
ensure a smooth even cut.  
By replacing the washer, then  
the half washer, then the nut  
securing the blade firmly,  
(25 – 30Nm) repeat this for  
the other 3 blades.  
6. Replace the blade disc and  
retighten the central blade bolt  
tightly (50 – 59Nm).  
Note. Use a wooden block to  
stop the blade from turning. The  
4 blades should be tightened fully but check to ensure they  
can still swing back if they were to hit a solid object.  
Where required tighten the bolts with a torque wrench,  
the centre disc blade bolt torque: 50 – 59Nm and the four  
blades torque: 25 – 30Nm.  
If you do not have a torque wrench ask a mower service  
dealer to tighten the blade bolts before you use the mower.  
WARNING. If the blade bolts are not tightened correctly  
they could loosen and/or come out and it would be possible  
for the blades to fly off while you are operating the mower.  
7. Return the mower to the upright position.  
8. Start the engine and allow the mower to run for a few  
minutes to check that the blade is properly fitted and that  
there is no undue noise or vibration. Use only the blade  
as recommended by the manufacturer.
